calculate the percent KBr in a solution containing 0.88 grams KBr per 800 mL solution.
mass solution=800g
mass KBr=.88
percent= .88/800 * 100
To calculate the percent KBr in a solution, you need to know the mass of KBr and the total mass of the solution.
Step 1: Convert the volume of the solution to grams
Since you have the volume of the solution given in milliliters (mL), you need to convert it to grams. The density of water is approximately 1 g/mL, so you can assume that 800 mL of water has a mass of 800 grams.
Step 2: Calculate the mass of KBr
The mass of KBr in the solution is given as 0.88 grams.
Step 3: Calculate the percent KBr
To calculate the percent KBr, divide the mass of KBr by the total mass of the solution, and then multiply by 100 to get the percentage.
percent KBr = (mass of KBr / total mass of solution) * 100
In this case, the mass of KBr is 0.88 grams, and the total mass of the solution is 800 grams.
percent KBr = (0.88 g / 800 g) * 100 = 0.11%
Therefore, the percent KBr in the solution is 0.11%.
